Is 8/7 greater than 2/9?
To compare two fractions, such as 8/7 and 2/9, there are two main common methods: the first one involves finding a common denominator, and the other one is to convert the fractions directly into decimal values.
1) Using the same denominator
- Multiply the numerator of the first fraction with the denominator of the second fraction: 8 × 9 = 72
- Multiply the numerator of the second fraction with the denominator of the first fraction 2 × 7 = 14
- Multiply the denominators of both fractions together: 7 × 9 = 63
- Rewrite both fractions with the new common denominator:
- 8/7 = 72/63
- 2/9 = 14/63
With a common denominator, the comparison becomes much simpler.
Since 72 is larger than 14, we can conclude that 8/7 is greater than 2/9.
2) Converting to decimal
